Coloring books for adults is an offspring of art therapy which is a mental health profession that is the process of making and creating artwork which intends to "explore feelings, reconcile emotional conflicts, foster self-awareness, manage behavior and addictions, develop social skills, improve reality orientation, reduce anxiety and increase self-esteem" (according to the American Art Therapy Association). So basically, it's similar to good old therapy. Also, art therapy is not only about mental health and improving yourself - it's a form of personal expression, as well.
Most homes will have coloring pencils or crayons. In my house we also have glitter pens, foam pens and most importantly paints for the kids to select between. Using paints will require a little bit more setup time as you may need to clear an area and lay newspapers down over the table to protect it.
You can also get dino coloring books and activities to buy - these make great birthday or Christmas gifts or treats on a rainy day. You can get a dinosaur T-shirt with washable markers than you can create your own design with over and over. Prehistoric posters colored by your child are also good fun. There's even a great dinosaur puzzle to color - our kids love puzzles and coloring so this is a great idea.
Without money, the commander cannot hope to sustain the war effort for any length of time. Engaging in a children's birthday party is a difficult proposition indeed because of the volumes of children involved, and so when you factor in food and entertainment for all the children the cost will quickly add up. This is why Winnie the Pooh coloring pages are such a wise investment indeed, they are extremely cheap and will be more than enough to keep the little ones amused for hours to come. Parents, you may want to keep the Winnie the Pooh coloring pages as a secret weapon to be used only in an emergency i.e. when you feel your morale beginning to plummet to an all time low. Just make sure that there is not a mass revolt on your hands because you failed to get the right kind of Winnie the Pooh coloring pages!
